Does exiting NodeJS main process causes all child processes to exist as well

Question

I'm creating a cluster in nodejs application & at some point I'll need to close all the child process(the cluster workers). I was wondering if calling process.exit(0) on the master process would be enough to close them all. I tried it & it's seems to work but I want to make sure that this wouldn't cause a memory leak of some kind

Answer 1

The child_process will continue even if node does not, see below:

NODE:

child_process.exec("sleep 20")
process.exit(0)

BASH:

ps aux | grep "sleep 20"

OUTPUT:

USERNAME       PID   CPU  MEM  VSZ    RSS TT  S     STARTED   TIME sleep 20

The sleep 20 is still shown as running.
